technically the question was "only out for a day hike, travelling light and not planning to spend the night out, How would you go about a shelter for the night (and fire in Scene 2) and what would you take with you in the way of emergency kit to enable this ???"
That's the kit I'd be carrying, and that's the solution I'd take
Without the kit (not going to happen) I should image I could still get back in Scenario 1 (aid of walking poles - if not perhaps try to find some poles to cut).
Scenario 2 - without any kit and without the option of moving what options are there? You can sit there and wait for the weather to improve (cold and miserable - how long until hypothermia?), or you can get on the phone, admit to being very irresponsible, and let a MRT find you. The answer is A improve nav skills beforehand and B carry kit
